perf record: Fix done_fd wakeup event

evlist__add_wakeup_eventfd() calls perf_evlist__add_pollfd() to add a
non-perf-event to the evlist pollfds. Since commit 415ccb58f6
("perf record: Introduce thread specific data array") that doesn't work
because evlist pollfs is not polled and done_fd is not duplicated into
thread-data.

Patch "perf record: Fix way of handling non-perf-event pollfds" added a new
approach that ensures file descriptors like done_fd are handled correctly
by flagging them as fdarray_flag__non_perf_event.

Fix by flagging done_fd as fdarray_flag__non_perf_event.

Example:

 Before:

  $ sleep 3 & perf record -vv -p $!
  ...
  thread_data[0x55f44bd34140]: pollfd[0] <- event_fd=5
  thread_data[0x55f44bd34140]: pollfd[1] <- event_fd=6
  thread_data[0x55f44bd34140]: pollfd[2] <- event_fd=7
  thread_data[0x55f44bd34140]: pollfd[3] <- event_fd=8
  thread_data[0x55f44bd34140]: pollfd[4] <- event_fd=9
  thread_data[0x55f44bd34140]: pollfd[5] <- event_fd=10
  thread_data[0x55f44bd34140]: pollfd[6] <- event_fd=11
  thread_data[0x55f44bd34140]: pollfd[7] <- event_fd=12
  ...

 After:

  $ sleep 3 & perf record -vv -p $!
  ...
  thread_data[0x55a8ded89140]: pollfd[0] <- event_fd=5
  thread_data[0x55a8ded89140]: pollfd[1] <- event_fd=6
  thread_data[0x55a8ded89140]: pollfd[2] <- event_fd=7
  thread_data[0x55a8ded89140]: pollfd[3] <- event_fd=8
  thread_data[0x55a8ded89140]: pollfd[4] <- event_fd=9
  thread_data[0x55a8ded89140]: pollfd[5] <- event_fd=10
  thread_data[0x55a8ded89140]: pollfd[6] <- event_fd=11
  thread_data[0x55a8ded89140]: pollfd[7] <- event_fd=12
  thread_data[0x55a8ded89140]: pollfd[8] <- non_perf_event fd=4
  ...

This patch depends on "perf record: Fix way of handling non-perf-event
pollfds".
